This invention teintes to e. method 0i anti nppetetus tot' pioviciing u, uniform isti-'b toution-ot fuel gos to byp'foduet eoiieovene ot the byproduct type, and has for its ob jeet the provision of a noiei method of anti appoint-us tot' providing a unit-erm distiiisution ot the tue zas to coke ovens ot the byni'otiut-t type whereby.'Y uniform heating of euch ot the ovens Wiii be obtoinefi.

tiiottiei object is to provide n method and iomtue, such deseuiiieci above, which u'iii ottuso xYi-eater gas economy; due to the netten tempe intuye regulation resulting" tron; impeovefi eontroi oit the gus di.

Experience has shown that in operating the ojpioctuct cette evene of the Koppels e similiar types, the ovens farthest fiom rteint of source ot the tttei gas were (i to n. ieee (ieggi'ee than the ovens doser soutee. v"tntiious experiments were nitide in en otteint to overcome this objection), The 'ptesemre vos i'eguiate eo :te to be substantiaiij/ constant and. the same through-l out the 'fuel ges moin, sind the ontiets to euch oven were teguiate. so es to be uniform, and ev n with an equal Voiume and interieure of ga entering into each oven they became progeesiveiy eooiei es they pro" grossed from tue source of supply.
